Westclox Canada Electric Alarm Clock- Model S4-C - 1936-Power Out Indicator

The Westclox Canada Electric Alarm Clock, Model S4-C, from 1936 is a vintage electric clock featuring an analog display. A notable and innovative feature for its time was the "Power Out Indicator." This indicator was a mechanical flag or small plate that would drop or change position when the clock's electric power was interrupted. Since the clock had no battery backup, a power outage would cause the time to become inaccurate. The "Power Out Indicator" served as a simple yet effective way for the user to know that the clock had lost power and that the time needed to be reset. This was a significant user-friendly feature in an era when home power outages were more common and digital clocks with blinking displays did not yet exist.
